With luck
About 10% of wildlife watchers report a Golden Flangetail sighting in Beijing on a given day, based on 46 verified sightings from GBIF citizen-science data. It is the 65th most-seen of the 401 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Golden Flangetail in Beijing on a given day, against under 5% in September to May, the lowest months. That is one of Beijing's wettest months, with about 85 mm of rain against almost none in January.
Among the best
Of the 7 cities where we can rate Golden Flangetail sightings, Beijing ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Nagoya (Japan, about 10%).
GBIF citizen-science records
It is estimated from how often the Golden Flangetail is recorded against all the insects logged in Beijing (46 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
